JS if shartlari

JavaScript if operatori

Shart rost bo‘lganda kod blokini bajarish uchun JavaScript if operatoridan foydalaning.

if (condition) {
// block of code to be executed if the condition is true
}

E’tibor bering, if kichik harflarda yoziladi. Katta harflar (If yoki IF) JavaScript xatosini keltirib chiqaradi.

Agar soat 18:00 dan kamroq bo‘lsa, "Xayrli kun" tabriklang:

if (hour < 18) {
greeting = "Good day";
}

Salomlashish natijasi quyidagicha bo‘ladi:

let age = 18;
let text = "You can Not drive";

if (age >= 18) {
text = "You can drive";
}

let age = 16;
let text = "You can Not drive";

if (age >= 18) {
text = "You can drive";
}

Boshqa if iborasida if operatoridan foydalanishingiz mumkin:

let age = 16;
let country = "USA";
let text = "You can Not drive!";

if (country == "USA") {
  if (age >= 16) {
    text = "You can drive!";
  }
}

If iboralari kodingizni murakkablashtirishi mumkin.

Eng yaxshi yechim mantiqiy AND operatoridan foydalanishdir:

let age = 16;
let country = "USA";
let text = "You can Not drive!";

if (country == "USA" && age >= 16) {
text = "You can drive!";
}

Yutuqlaringizni kuzating – bu bepul!
